drm/amd/display: pass calculated dram_speed_mts to dml2

Browse source

[ Upstream commit b40d022ec0 ]

[why]
currently dml2 is using a hard coded 16 to convert memclk to dram_speed_mts.
for apu, this depends on wck_ratio.

change to pass the already calculated dram_speed_mts from fpu to dml2.

v2: use existing calculation of dram_speed_mts for now to avoid regression
